I study mathematics and computer science, and I'm starting to learn japanese. Could you suggest me dictionaries/sites/etc where I could learn terminology on these subjects?

OFF TOPIC: Not exactly about Japanese language per se, but more so about finding references for Japanese. –  Mark Hosang Jun 7 '11 at 6:56
    
See this question on meta; I think the jury's still out on what constitutes an on-topic resource question. FWIW, I think this one is valid. –  Amanda S Jun 7 '11 at 7:07
    
thanx amanda, i actually just saw this question float back up to top on meta. so i'm going to remove the off-topic (if i can). Apparantly, i can't remove my vote to close. But according to the consensus, this seems to be on topic. Sorry for the confusion _|-|o –  Mark Hosang Jun 7 '11 at 8:01

EDICT (which is the corpus JquickTrans apparently uses) has several special dictionaries for technical terms. The "Computing/Telecomms" dictionary includes such wonderful words as:

変数設定 【へんすうせってい】 (n) variable initialization
参照渡し 【さんしょうわたし】 (n) call by reference
オブジェクト[指向]{しこう}プログラミング (n) object-oriented programming

I always check Weblio's dictionary for a lot of great real-world examples of technical terms. I haven't looked into what the sources are exactly, but they seem to have a lot of technical corpora that I haven't seen anywhere else.

If you are not a computer nerd, but want to know academically, I think 岩波数学辞典 is the standard for mathematics.

It's so expensive, though, and the reviews don't indicate its scope (abstract math? applied math? graduate level?) –  Trevor Alexander Feb 26 '13 at 20:53

It is a little bit informal, but the language site that I always use to look up some word in Japanese is alc.co.jp

It uses the Eijiro dictionary, and has pretty good coverage on many subjects.

Hope this helps.

@YOU Yes, this service is very popular among the Japanese. Combined with a plugin like rikaikun or rikaichan it is an essential everyday tool for my work. –  wallyqs Jun 7 '11 at 10:57

I don't know about math, but at my company, (where i am the only english speaker) everyone understands the katakana versions of the english words without even knowing english. If you come to japan though, there are actually tons of Japanese dictionaries specifically for programming terms.

I have been using JquickTrans dictionary software for years (had to pay $15 before but it's freeware now), and it has a few specialized dictionary catalogs that could be useful to find science and math terms:

FFT

REGEX

EXP
